I heard that colors have meanings in Judaism. What is the history behind this and could you explain the meaning of certain colors like red, green, blue, yellow, violet, black, orange, and white.

Dear Name@Withheld,

The color red represents blood and sin. White represents purity from sin. Ironically, a white skin coloration marks a person impure, making him into a "metzorah" (leper). Blue is the color of sky and hence of spirituality, reminding of "G-d's Throne of Glory."
